2-[(1R)-1-Chloroethyl]-3-fluoropyridine → HCID 25064543, compound

Participants

Reaction Steps

The title compound was prepared using General method A starting from (2R)-2-[(2-amino-5-mercapto[1,3]thiazolo[4,5-d]pyrimidin-7-yl)amino]-4-methylpentan-1-ol (348 mg, 1.16 mmol) and 2-((R)-1-chloroethyl)-3-fluoro-pyridine (240 mg, 1.5 mmol). Purification by flash column chromatography (eluent DCM:methanol gradient) resulted in 190 mg (47% yield) of the title compound with a diastereomeric excess of 60%. Of this material 55 mg was further purified by preparative HPLC. The last eluting isomer was collected to yield 21 mg of the title compound.
